Spring-loaded quarter holder, holds a full $10 roll (40 coins). Remixed from US Quarter Dispenser w/ Belt Clip by blazin64.
I printed it in PLA at .16mm layer height, but .2 is probably fine. 25% infill for extra strength; I used gyroid. I used painted-on support enforcers for the coin slot, otherwise prints fine with no other supports. Best way to detach the small parts from the bed if you've got a glass print bed like me is to stick the end of the tube onto the plug or cap and pop it off. 3MF file includes my print settings; brim is probably not needed.
Cap threads need a little wearing in because it wedges really tight on the last quarter-turn or so; I recommend hand-tightening until you feel resistance and then using a quarter held with pliers to turn it back and forth gently until it seats fully and can be easily unscrewed.
The author remixed this model.
I removed the belt clip from the original model by blazin64 and added a larger hole to the cap to wedge in the end of a 19mm spring so it doesn't just fall out when you open it. .
